Howdy,





Thanks for the advice.



I did as you suggested.



Runing squeak.sh I just noticed the following in the xterm from which I launced it:





/usr/lib64/libc.so tryLoading //usr/lib64/libc.so: dlopen: //usr/lib64/libc.so: invalid ELF header



I have no idea 


I removed the leading '/'  due to the dlopen: //  message, but same result  different output.

usr/lib64/libc.so tryLoading /usr/lib64/libc.so: dlopen: /usr/lib64/libc.so: invalid ELF header



cheers.

Hmm... you might want to try a fully qualified path? At least that's required in Ubuntu ... if you have an idea on how to improve CStandardLibrary class >> #guessModuleName, feel free to share it here. :-)

Do other libraries load through FFI?



Best,

Marcel

I forgot to mention that I changed the entry in Preferences -> FFI Libraries  -> C runtime/standard library (aka.CRT and libc)  from the original libc.so.6 to my systems' libc.soC standard library not available. Please check module name in preferences.





ls /usr/lib64/libc.*

/usr/lib64/libc.a  /usr/lib64/libc.s





cheers.

Hi folks





I downloaded the latest Squeak from trunk (looking good btw, and very fast)



After installation and adding the options in the wizard, I am getting:



C standard library not available. Please check module name in preferences.



Error: External module not found









I am running Slackware Linux 64. Slackware has an oddity about it in that the core libraries are in /lib64 instead of /lib in case you suspect its a path issue.
